Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage groove buried in the floor of a commercial kitchen, a food factory or the like.

[0002]

2. Description of the Related Art In commercial kitchens and food factories, it is important to cook and process food in a clean environment. For that purpose, the commercial kitchen and the food factory must be kept clean at all times. In order to maintain such a clean condition, hygienic maintenance of the drainage system is of utmost importance, and general public supervision is becoming strict.

However, as shown in FIGS. 9 and 10, a groove 21 having a substantially rectangular cross section is formed on the floor surface forming a part of the drainage system of a conventional commercial kitchen or food factory. 21
A step portion 23 on which the lattice lid 22 is placed is formed at the edge of the. The floor surfaces 24 on both sides of the groove 21 are set so as to descend to the groove 21 with a gentle slope.
The food leftovers and the like that have fallen to the inside are introduced into the groove 21 through the grid 25 of the grid lid 22 with cleaning water or the like, collected in the basin, and then drained to the outside.

[0004]

However, the above-mentioned lattice lid 2 is used.
2 and the gap 26 between the stepped portion 23 of the groove 21, and the grid lid 2
Food lattices and the like are clogged in the second grid 25, and by self-digesting them, they become a culture medium of bacteria and the bacteria propagate and spoil to give off a bad odor. Then, the worker or the like who walks on the lattice lid 22 uses the propagated bacteria for the floor surface 2 other than the groove 21.
By moving to 4, the bacteria will propagate throughout the room, and due to scattering, there are many opportunities for bacteria to easily attach to foods placed on food shelves, tables, etc. It promotes food spoilage and increases the risk of food poisoning.

Further, since the groove 21 is made of concrete itself, the surface of the groove 21 has a rough surface so that food residues and the like are easily adhered, and the adhered food residues and the like are self-digested. In this case, as in the above, the bacteria become a good medium and the bacteria grow, and the grown bacteria scatter in the room, which promotes the spoilage of foods and increases the risk of food poisoning.

Further, as described above, since the surface of the groove 21 is a rough surface, it is difficult to completely remove the food residue left over by a brush or the like even during cleaning.

The present invention has been made in order to solve the above problems of the prior art, and an object thereof is to provide a drainage groove having a groove structure which reduces the chances of bacterial growth at low cost.

[0008]

In order to achieve the above object, the present invention is directed to a smooth surface provided below the floor surface by opening a narrow groove slot formed along the axial direction upward. A groove main body having an inner wall, and a groove introduction portion having a smooth inner wall surface provided so as to rise from both side edges of the groove opening of the groove main body and form a narrow and narrow opening on the floor surface. The drainage ditch is embedded in the concrete floor.

[0009]

In the above structure, the drainage flowing after cleaning the equipment in the room and flowing it to the floor surface and cleaning the floor surface from the horizontal groove introduction part along with the floor slope along with food leftovers etc. Water is guided to the groove body through the vertical introduction part and is drained to the outside. At this time, since the inner wall surfaces of the introduction portion and the groove body are smooth surfaces, frictional resistance is small, and food leftovers and the like are smoothly discharged to the outside without stopping. Further, the opening along the floor surface of the groove and the groove introducing portion leading to the groove is narrow and does not hinder the walking of the worker even if the lid is not covered, and there is room for bacteria to propagate in the opening. Since the workers do not walk, bacteria are not transferred to the floor by walking, and the room is kept clean at all times.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings.

FIG. 2 is a plan view of the floor of the kitchen in which the drainage groove according to the present invention is installed. The drainage groove 2 is buried in the center of the floor 1, and the downstream end and the outside of the drainage groove 2 respectively. A grid 3 is embedded in the floor 1 so as to communicate with each other.

The floor 1 is composed of four slope portions 1a, 1b, 1c, 1d having a gentle slope (slope) surface that descends from the four sides with respect to the drainage groove 2.

As shown in FIG. 1, the drainage groove 2 has a pipe-shaped groove body 4 having an inner wall surface of a smooth surface, and a groove opening formed in a narrow width along the axial direction above the groove body 4. 5, a substantially vertical groove introduction portion 6 having inner surfaces of smooth surfaces rising from both side edges of the groove opening 5 to the concrete floor surface FL and guiding the drainage of the floor surface FL into the groove body 4. The groove introduction part 6 is formed by an approximately horizontal groove introduction part 7 continuous to the floor surface FL which is bent outward from the upper end of the groove introduction part 6 and descends at a gentle slope.

The groove main body 4 and the groove introducing portions 6 and 7 which are the constituent portions of the drainage groove 2 are integrally molded using stainless steel as a raw material, and the dimensions of each constituent portion are, for example, a diameter of the groove main body 4 of 150 mm. , Axial length 5000 mm, groove 5
Width of 25 mm, the distance 25 between the inner wall surfaces 6a and 6b of the groove introduction part 6
mm, the width of each horizontal 7a, 7b of the groove introduction portion 7 is 30 mm, and the height difference between the upstream end and the downstream end of the groove introduction portion 6 is set to 75 mm. Therefore, in this embodiment, the gradient of the groove body 4 is 75/5000.

A general manufacturing method of the drainage groove 2 is a ready-made stainless steel pipe (not shown) (for example, diameter 150 mm).
A small width (for example, 25 mm) opening is cut upward along the axial direction to manufacture a component corresponding to the groove main body 4 shown in FIG. 1. Also, a horizontal width (for example, 30 mm) is separately prepared by using a stainless steel plate. ) And a vertical wall, and the vertical wall is provided with a gap (for example, 75 mm) from the horizontal width portion at an interval (for example, 5000 mm) in the front and back to form a vertical wall. On the lower edge of the slope (eg 75/500
0) is provided, a component portion corresponding to the groove introduction portion consisting of a pair of symmetrical horizontal width portions 7 and vertical walls 6 shown in FIG. 1 is manufactured, and subsequently, an opening portion of the component portion corresponding to the groove body 4 is manufactured. This is achieved by welding 8 along the edge the sloped lower edge of the component corresponding to the groove introduction.

In the above manufacturing method, instead of notching a narrow opening above the ready-made stainless pipe, one cut line is provided above the ready-made stainless pipe along the axial direction, As shown in FIG. 6, it is also possible to fold the cut line portion upward to provide a groove opening 5 and butt weld the welded portion 4a, 4b with the inclined lower edge.

As another method of forming the drainage groove 2,
The pipe-shaped groove main body 4 and the folded-back portions 4a and 4b rising on both side edges of the groove opening 5 are integrally formed from a single stainless steel plate, and the groove-introduced portion 6 having the slope is formed in the folded-back portions 4a and 4b.
The lower edges may be butted and welded 8 as shown in FIG.

Further, as another method of forming the drainage groove 2,
The central portion of one stainless steel plate is bent into a pipe-shaped groove body 4 and a groove opening 5 is formed in the groove body 4.
It is also possible to continuously bend the vertical groove introducing portion 6 and the continuous horizontal groove introducing portion 7, respectively.

The drainage groove 2 may be formed as an integral elongated member having an axial length extending from upstream to downstream, but a plurality of divided drainage members are sequentially connected in series to form a long length. Sometimes it is a scale. Especially when the room is large, the drainage groove 2 is constructed by the latter connection method.

As described above, the use of stainless steel as the raw material for the respective constituent parts of the drainage groove 2 (the groove main body 4, the groove introduction portions 6, 7) is for discharging food leftovers and the like from the kitchen floor surface 1 to the outside. This is because the surfaces, wall surfaces and inner surfaces of the drainage grooves 2 are made smooth in order to reduce the frictional resistance between the food residues and the like and the drainage grooves 2.

Further, narrowing the opening 9 of the groove opening 5 and the groove introduction portion 6 with respect to the diameter of the groove main body 4 makes the structure of the drainage groove 2 which does not hinder the walking of the worker without the lid. This is because the structure of the lid and the fitting step portion of the lid (see FIGS. 9 and 10) serving as a culture medium for bacteria is positively omitted.

In constructing the drainage groove 2, as shown in FIG. 3, when the reinforcing bar 10 of the floor 1 is assembled, a support frame 13 including a leg portion 11 and a receiving portion 12 is also incorporated, Receiver 1
After setting the slope of the groove main body 4 and the positions of the groove mouth 5 and the opening 9 of the groove introducing portion 6 by 2 respectively, the concrete 14
Is added to the surface of the concrete 14 so that the surface of the concrete 14 is gently sloped and the horizontal groove introduction portion 7 is continuously formed.

The drainage groove 2 can also be installed in the existing drainage groove 15. In that case, as shown in FIG. 5, after setting the gradient of the groove main body 4, the position of the groove opening 5 and the opening 9 of the groove introducing portion 6 in the existing drainage groove 15 through the support frame 13, respectively, are properly set. The concrete 14 is poured into the existing drainage groove 15, and the surface of the concrete 14 is continuously finished to the existing floor surface FL and the horizontal groove introduction portion 7 at a gentle gradient.

At the upstream end of the drainage groove 2, as shown in FIG. 4, the groove opening 5 of the groove main body 4 is located at a depth of 25 mm below the floor surface FL, and the groove introduction portion 6 above the groove opening 5 is located. The drainage of food residues and the like on the sloped portion 1a on the upstream side of the floor 1 is configured to flow into the opening 9, and the opening of the groove introduction portion 6 is formed on both left and right sides of the entire length of the drainage groove 2 from the upstream side to the downstream side. The left and right rims of the floor 9 are configured so that drainage of food leftovers and the like on the left and right slope portions 1b and 1c of the floor 1 flows into the rim 9, and
The downstream end of the is connected to the basin buried under the floor surface FL.

The basin 3 comprises an upper water collecting basin 16 and a lower draining basin 17. The downstream end of the drainage groove 2 is connected to the side of the water collecting basin 16, a grid-like lid 18 is capped on the upper side, and the detachable strainer 1 is on the lower side.
9 is attached and faces the upper part of the drainage basin 17 below.

The drainage basin 17 has the strainer 1 on the upper side.
It is connected to the lower side of the water collecting basin 16 via 9 and the side is connected to the outside.

The grid-like lid 18 has a slope portion 1d on the downstream side of the floor 1 and right and left slope portions 1b, 1 adjacent to the slope portion 1d.
It is configured so that the waste water such as food leftovers of c can flow in.

The groove body 4 of the drainage groove 2, the groove introduction portion 6,
Although each constituent part such as 7 is made of stainless steel as a raw material, it is not limited to stainless steel as long as each constituent part has a smooth surface, and other raw materials such as synthetic resin can be selected.

The drainage groove 2 may be formed by successively joining a plurality of concrete blocks (not shown). In this case, the groove wall surface is formed by each concrete block itself to form a smooth surface. The smooth surface can be formed by adjusting the cement ratio or by polishing the groove wall surface, but a synthetic resin pipe can be fitted in each concrete block, or a synthetic resin sheet can be lined. .

Further, in the embodiment, the cross-sectional shape of the groove main body is circular, but it is not limited to this.

Next, the operation of the above-mentioned embodiment will be described.

When water is sprayed on the surface of the floor 1, the slopes 1a, 1b, 1c, 1 of the floor 1 on which food residues and the like are attached are attached.
d is washed with the sprayed water, and the water becomes drainage mixed with washed food residues and the like, passes through the horizontal groove introduction portion 7 of the drainage groove 2, and becomes a narrow narrow strip. Water is collected in the opening 9 of the.

Since the opening 9 is not covered with a lid, the drainage flows directly from the opening 9 into the vertical groove introduction portion 6, is guided by the vertical inner wall surfaces 6a and 6b, and passes through the groove opening 5 to form the groove. It flows into the main body 4.

At this time, since the surfaces of the horizontal groove introducing portion 7 and the inner wall surfaces 6a, 6b of the vertical groove introducing portion 6 are all smooth surfaces, the resistance of food residues and the like is reduced during cleaning drainage. Even without stopping, it is easily transferred to the groove body 4.

The drainage in the groove main body 4 is collected in the water collecting basin 16 due to its gradient. At this time, since the groove main body 4 has a circular cross-sectional shape and has a smooth surface, food residues and the like can easily flow into the water collecting basin 16 with less resistance.

The waste water collected in the water collecting basin 16 is filtered by a strainer 19 for food residues and the like, dropped into the water discharging basin 17, and then discharged to the outside.

Since the inside of the groove main body 4 is a smooth surface, when cleaning, the main body 20a of the cleaner 20 having the flat shape and along the cross section of the groove main body 4 shown in FIG. 6 is inserted into the groove main body 4 and rotated by 90 degrees to form the handle portion 20.
All the inner walls in the groove body 4 can be easily cleaned by grasping b and moving it from the upstream side to the downstream side of the opening 5.

[0038]

As described above, in short, according to the present invention, the groove having the inner wall of the smooth surface provided below the floor surface is formed by opening the narrow groove opening formed along the axial direction upward. Drainage because it is composed of a main body and a groove introduction section having an inner wall surface of a smooth surface provided so as to rise from both side edges of the groove opening of the groove main body and form a narrow and narrow opening on the floor surface. The floor cleaning wastewater guided into the groove flows into the groove main body of the drain groove without stopping food leftovers or the like in the narrow groove introduction portion of the drain groove, and even in the groove main body. There is no room for bacteria to flow into the basin without stopping. Therefore, unlike the conventional case, the labor for removing the groove lid and the labor for cleaning the inner wall of the groove can be omitted to facilitate the cleaning, and since the operation for removing the lid can be omitted, bacteria are not scattered. For workers working on the floor, the opening of the narrow groove introduction part not only does not hinder walking, but it may become a breeding medium for migrating bacteria during walking. A small amount keeps the room clean, and food and the like are handled hygienically.
